Introduction

Seasonic continues to expand their popular X Series power supply line up with the introduction of four new models: 560W, 660W, 760W and 850W targeted towards users looking for performance, high efficiency and quiet operation. These new power supplies complement the original X Series (750W and 850W) along with the X Series fanless 400W and 460W units. Seasonic's new X Series line brings several major advancements to the standard PC PSU platform.

Here is what Seasonic has to say about their new X Series 560, 660, 760 & 850 watt Power Supplies: "Versatility best describes these mid range power output 80 Plus Gold certified power supplies. These fully modular units provide enough juice to run just about any system configuration you build. Manufactured with top-grade components such as the Sanyo Denki – San Ace fan, governed by Seasonic's semi-passive Hybrid Silent Fan control, these units will just keep on working day in and day out."

PSU Testing Methodology

Establishing an accurate load is critical to testing and evaluating a PC power supply. PCPerspective’s power supply test bench can place a precise 2,000 watt DC load on the PSU under test. Each power supply is tested under controlled, real-world conditions up to its maximum rated load, using both 115 VAC and 240 VAC line voltage. Our current suite of tests includes:

• DC Load Regulation

• DC Line Regulation

• DC Cross-load (unbalanced load)

• AC Ripple and Noise

• Power Factor

• Efficiency

• Differential Temperature

• Noise

The Seasonic X Series 560W power supply was evaluated on both features and performance. A full range of equipment was used to test the power supply under controlled load conditions.
